Bridgeport 12190182 Pinion Shaft Hub Screw Milling

Product Description

The BRIDGEPORT 12190182 is a pinion shaft hub screw designed as a direct OEM-style replacement component for Bridgeport milling machines. This hardware fastener secures the pinion shaft hub assembly, maintaining proper alignment and retention within the machine's head or knee drive mechanism. Weighing 0.2 pounds, it is a small but critical piece of hardware that machinists and machine tool technicians install during routine maintenance or component rebuilds. Correct fitment and seating of this screw ensures the integrity of the shaft-to-hub connection under operational load.

This screw is intended for use with Bridgeport I Series milling machines, classified under accessory type as a pinion shaft hub screw for basic machine configurations. It is typically installed during head disassembly, quill service, or knee-feed rebuilds where the pinion shaft hub must be removed and refastened. Machine shops, tool-and-die facilities, and industrial maintenance teams are the primary end users for this type of replacement hardware.
